Diversity of sponges (Porifera) from cryptic habitats on the Belize barrier reef near Carrie Bow Cay

Research on the Belize Barrier Reef near Carrie Bow Cay reveals that cryptic habitats, such as shaded coral rubble and crevices, host a significant portion of sponge diversity. Of the 122 sponge species identified from samples collected between 1972 and 2012, 61% are exclusive to these dark or shaded environments, while 39% also inhabit light-exposed areas. This cryptic fauna constitutes approximately 38% of the estimated 200 sponge species in the region. Notably, 14 new species were discovered, including one new genus, highlighting the reef's unexplored biodiversity. The study underscores the importance of cryptic habitats in supporting high species diversity and contributes to our understanding of marine ecosystem complexity.
